Description

Technical Field

[0001] This utility model relates to the technical field of magnetic polishing equipment, specifically to a mesh plate support structure for a magnetic force generating device. Background Technology

[0002] Magnetic polishing equipment is a surface treatment device that uses a high-speed rotating magnetic field to drive magnetic needles to impact workpieces at high frequency. It can remove burrs and oxide films from the workpiece surface and perform polishing and cleaning, achieving a seamless finish without damaging the workpiece's precision. Existing magnetic polishing equipment typically includes a circulating transmission device and a magnetic force generating device. The circulating transmission device has a material box containing the magnetic needles and workpieces, which rotate cyclically with the transmission device. When passing the magnetic force generating device, the magnetic needles in the material box move at high frequency, polishing the workpiece.

[0003] Because the magnetic needles inside the material box are prone to detaching during high-frequency movement, a mesh plate needs to be installed above the magnetic force generator to prevent them from falling into it. The mesh plate is supported by crossbars on the frame to prevent falling needles from damaging the magnetic force generator. To minimize the influence of the mesh plate on the magnetic field, it is relatively thin. Since the mesh plate is supported by crossbars on both sides, it is prone to denting in the middle after repeated impacts from the magnetic needles, and may even come into contact with the high-speed rotating permanent magnets on the magnetic force generator, causing equipment damage. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a mesh support structure that can effectively support the mesh and prevent it from contacting the magnetic force generating device.

[0005] The technical solution of this utility model is to provide a mesh plate support structure for a magnetic force generating device, which has the following structure, is set on the frame and is located between the mesh plate and the magnetic force generating device; The mesh support structure includes a support plate connected to the frame, with its top abutting against the bottom of the mesh for supporting the mesh; the support plate has a circular through hole penetrating its upper and lower end faces, through which the magnetic field generated by the magnetic force generating device passes.

[0006] By adopting the above structure, the mesh plate support structure for the magnetic force generating device of this utility model has the following advantages compared with the prior art: This invention features a support plate located below the screen plate. Compared to the crossbars on the frame, the support plate has a larger support area, providing better support for the screen plate. At the same time, the through holes on the support plate allow the magnetic field generated by the magnetic force generating device to pass through without affecting the strength of the magnetic field, thus ensuring the efficiency and quality of the grinding process.

[0007] Preferably, the support plate includes a plate body, the two sides of the plate body are bent downward to form a first folded edge, the two ends of the plate body are bent downward to form a second folded edge, and the ends of adjacent first folded edges and second folded edges are connected to each other.

[0008] The support plate adopts this structural design, making it resemble an inverted cap. While ensuring sufficient strength, it can reduce the thickness of the support plate and save materials. At the same time, the cavity it forms can also allow the upper end of the magnetic force generating device to extend into, reducing the distance between the magnetic force generating device and the upper material box, and further improving the high-frequency vibration of the magnetic needles in the material box.

[0009] Preferably, the first folded edge is provided with a mounting hole extending along the height direction of the first folded edge; a fixing screw is provided in the mounting hole, and the connecting end of the fixing screw passes through the mounting hole and is threaded into the screw hole of the frame. With this configuration, the user can fine-tune the installation height of the support plate according to the requirements to make it conform to the actual production needs.

[0010] Preferably, the mounting holes are in two sets, with each set of mounting holes symmetrically arranged at both ends of the corresponding first fold, so that the force on the support plate is more even, thereby ensuring its stable installation.

[0011] Preferably, a horizontal window is provided in the middle of the first folded edge, and the horizontal window extends vertically downward and penetrates the lower end face of the first folded edge. Since the cavity at the lower end of the support plate can allow the upper end of the magnetic force generating device to extend into it, a horizontal window is provided on the first folded edge. This facilitates observation of the position of the upper end face of the magnetic force generating device without affecting its strength, and avoids contact between it and the bottom of the plate, which could cause damage to the equipment.

[0012] Preferably, the magnetic force generating device includes a magnetic disk and a drive motor. A plurality of permanent magnets are evenly spaced on the magnetic disk, and the output shaft of the drive motor is connected to the central shaft of the magnetic disk to drive the permanent magnets on the magnetic disk to rotate circumferentially.

[0013] Preferably, the through hole is the same size as the magnetic disk, so that its size is minimized as much as possible without affecting the magnetic field, thereby increasing the contact area between the support plate and the mesh plate. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. At the same time, the terms "first", "second", etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown; This utility model discloses a mesh plate support structure for a magnetic force generating device: it is set on the frame 1 and located between the mesh plate 2 and the magnetic force generating device 3.

[0022] The mesh support structure includes a support plate 4, which is connected to the frame 1 and its top abuts against the bottom of the mesh plate 2 to support the mesh plate 2. The support plate 4 is provided with a circular through hole 5 that penetrates its upper and lower end faces, through which the magnetic field generated by the magnetic force generating device 3 passes.

[0023] This invention provides a support plate 4 below the mesh plate 2. Compared with the crossbar on the frame, the support plate 4 has a larger support area, which can better support the mesh plate 2. At the same time, the through holes 5 on the support plate 4 allow the magnetic field generated by the magnetic force generating device 3 to pass through without affecting the strength of the magnetic field, thereby ensuring the efficiency and quality of grinding.

[0024] like Figure 4As shown, the support plate 4 includes a plate body 41. Both sides of the plate body 41 are bent downwards to form first folded edges 42, and both ends of the plate body 41 are bent downwards to form second folded edges 43. The ends of adjacent first folded edges 42 and second folded edges 43 are connected to each other. This structural design of the support plate 4 gives it an inverted lid shape, which, while ensuring sufficient strength, reduces the thickness of the support plate 4, saving material. Simultaneously, the resulting cavity allows the upper end of the magnetic force generating device 3 to extend into, reducing the distance between the magnetic force generating device 3 and the upper material box, further enhancing the high-frequency vibration of the magnetic needles inside the material box.

[0025] The first folded edge 42 is provided with a mounting hole 44, which extends along the height direction of the first folded edge 42. A fixing screw (not shown in the figure) is provided in the mounting hole 44, and the connecting end of the fixing screw passes through the mounting hole 44 and is threaded into the screw hole of the frame 1. With this setting, the user can fine-tune the installation height of the support plate 4 according to the requirements to make it meet the actual production needs.

[0026] There are two sets of mounting holes 44, with each set of mounting holes 44 symmetrically arranged at both ends of the corresponding first folded edge 42, so that the force on the support plate 4 is more even, thereby ensuring its stable installation.

[0027] A horizontal window 45 is provided in the middle of the first folded edge 42. The horizontal window 45 extends vertically downward and passes through the lower end face of the first folded edge 42. Since the cavity at the lower end of the support plate 4 can allow the upper end of the magnetic force generating device 3 to extend into, a horizontal window 45 is provided on the first folded edge 42. Without affecting its strength, this facilitates observation of the position of the upper end face of the magnetic force generating device 3 and avoids it from contacting the bottom of the plate 41, which could cause damage to the equipment.

[0028] For example Figure 2 and Figure 3 As shown, the magnetic force generating device 3 includes a magnetic disk 31 and a drive motor 32. A plurality of permanent magnets 33 are evenly spaced on the magnetic disk 31. The output shaft of the drive motor 32 is connected to the central shaft of the magnetic disk 31, driving the permanent magnets 33 on the magnetic disk 31 to rotate circumferentially. The inner diameter of the through hole 5 is the same as the outer diameter of the magnetic disk 31, allowing the size of the through hole 5 to be minimized without affecting the magnetic field, thereby increasing the contact area between the support plate 4 and the mesh plate 2.

[0029] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
